A Watershed Protection Plan for the Pecos River in Texas A Watershed Protection Plan for the Pecos River in Texas October 2008 A Watershed Protection Plan for the Pecos River in Texas Funded By: Texas State Soil and Water Conservation Board (Project 04-11) U.S. Environmental Protection Agency Investigating Agencies: Texas AgriLife Extension Service Texas AgriLife Research International Boundary and Water Commission, U.S. Section Texas Water Resources Institute Prepared by: Lucas Gregory, Texas Water Resources Institute and Will Hatler, Texas AgriLife Extension Service Funding for this project was provided through a Clean Water Act §319(h) Nonpoint Source Grant from the Texas State Soil and Water Conservation Board and the U.S. Environmental Protection Agency. Acknowledgments The Investigating Agencies would like to take this opportunity to thank the many individuals who have contributed to the success of this project. The development of this watershed protection plan would not have been possible without the cooperation and consolidation of efforts from everyone involved. First, we would like to thank the many landowners and other interested parties who have attended project meetings, participated in surveys, and provided invaluable input that has guided the development of this document. Your interest in this project and the Pecos River was and will continue to be instrumental in ensuring the future restoration and improvement of the health of this important natural resource. While there are too many of you to name here, we hope that your interest, involvement, and willingness to implement needed management measures will grow as progress is made and new phases of the watershed protection plan are initiated. Our gratitude is extended to the following individuals who have contributed their support, technical expertise, time, and/or advice during the project: Greg Huber, J.W. Thrasher, Bruce Moring, Steve Byrns, Bill Davis, Cory Horan and the Texas Commission on Environmental Quality (TCEQ) Clean Rivers Program team, and all Texas AgriLife Extension Service county agents located in the Pecos River watershed. We also recognize the following entities for their cooperation or contributions: Upper Pecos Soil and Water Conservation District (SWCD), Crockett SWCD, Red Bluff Water and Power Control District (WPCD), Pecos Valley Resource Conservation and Development (RC&D), U.S. Geological Survey, Texas Forest Service, TCEQ, and USDA-Natural Resources Conservation Service. Additionally, we extend our thanks to the municipalities of Del Rio, Fort Stockton, Imperial, Iraan, Mentone, Ozona, and Pecos and to Independence Creek Nature Preserve for the use of their facilities to conduct project meetings.

    THE NATIVE FISH FAUNA OF MAJOR DRAINAGES EAST OF THE CONTINENTAL DIVIDE IN NEW MEXICO A Thesis Presented to the Graduate Faculty of Biology Eastern New Mexico University In Partial Fulfillment of the Requirements fdr -the7Degree: Master of Science in Biology by Michael D. Hatch December 1984 TABLE OF CONTENTS Page Introduction Study Area Procedures Results and Discussion Summary Acknowledgements Literature Cited Appendices Abstract INTRODUCTION r (t. The earliest impression of New Mexico's native fish fauna =Ems during the 1850's from naturalists attached to various government survey parties. Without the collections from these and other early surveys, the record of the native fish fauna would be severely deficient because, since that time, some 1 4 native species - or subspecies of fish have become extirpated and the ranges of an additionial 22 native species or subspecies have become severly re- stricted. Since the late Miocene, physiographical changes of drainages have linked New Mexico, to varying degrees, with contemporary ichthyofaunal elements or their progenitors from the Rocky Mountains, the Great Plains, the Chihuahuan Desert, the Mexican Plateau, the Sonoran Desert and the Great Basin. Immigra- tion from these areas contributed to the diversity of the state's native ichthyofauna. Over the millinea, the fate of these fishes waxed and waned in ell 4, response to the changing physical and _chenaca-l-conditions of the surrounding environment. Ultimately, one of the most diverse fish faunas of any of the interior southwestern states developed. Fourteen families comprising 67 species of fish are believed to have occupied New Mexico's waters historically, with strikingly different faunas evolving east and west of the Continental Divide.

  • Stormwater Management Program 2013-2018 Appendix A
    Appendix A 2012 Texas Integrated Report - Texas 303(d) List (Category 5) 2012 Texas Integrated Report - Texas 303(d) List (Category 5) As required under Sections 303(d) and 304(a) of the federal Clean Water Act, this list identifies the water bodies in or bordering Texas for which effluent limitations are not stringent enough to implement water quality standards, and for which the associated pollutants are suitable for measurement by maximum daily load. In addition, the TCEQ also develops a schedule identifying Total Maximum Daily Loads (TMDLs) that will be initiated in the next two years for priority impaired waters. Issuance of permits to discharge into 303(d)-listed water bodies is described in the TCEQ regulatory guidance document Procedures to Implement the Texas Surface Water Quality Standards (January 2003, RG-194). Impairments are limited to the geographic area described by the Assessment Unit and identified with a six or seven-digit AU_ID. A TMDL for each impaired parameter will be developed to allocate pollutant loads from contributing sources that affect the parameter of concern in each Assessment Unit. The TMDL will be identified and counted using a six or seven-digit AU_ID. Water Quality permits that are issued before a TMDL is approved will not increase pollutant loading that would contribute to the impairment identified for the Assessment Unit. Explanation of Column Headings SegID and Name: The unique identifier (SegID), segment name, and location of the water body. The SegID may be one of two types of numbers. The first type is a classified segment number (4 digits, e.g., 0218), as defined in Appendix A of the Texas Surface Water Quality Standards (TSWQS).

  • Promise Beheld and the Limits of Place
    Promise Beheld and the Limits of Place A Historic Resource Study of Carlsbad Caverns and Guadalupe Mountains National Parks and the Surrounding Areas By Hal K. Rothman Daniel Holder, Research Associate National Park Service, Southwest Regional Office Series Number Acknowledgments This book would not be possible without the full cooperation of the men and women working for the National Park Service, starting with the superintendents of the two parks, Frank Deckert at Carlsbad Caverns National Park and Larry Henderson at Guadalupe Mountains National Park. One of the true joys of writing about the park system is meeting the professionals who interpret, protect and preserve the nation’s treasures. Just as important are the librarians, archivists and researchers who assisted us at libraries in several states. There are too many to mention individuals, so all we can say is thank you to all those people who guided us through the catalogs, pulled books and documents for us, and filed them back away after we left. One individual who deserves special mention is Jed Howard of Carlsbad, who provided local insight into the area’s national parks. Through his position with the Southeastern New Mexico Historical Society, he supplied many of the photographs in this book. We sincerely appreciate all of his help. And finally, this book is the product of many sacrifices on the part of our families. This book is dedicated to LauraLee and Lucille, who gave us the time to write it, and Talia, Brent, and Megan, who provide the reasons for writing. Hal Rothman Dan Holder September 1998 i Executive Summary Located on the great Permian Uplift, the Guadalupe Mountains and Carlsbad Caverns national parks area is rich in prehistory and history.

The bridge de igner of today is both artist and engineer. He understands the potential for strength and beauty which is inherent in steel structures, and he knows that aesthetic appearance can be achieved at no sacrifice of efficiency or economy. The simple grace of a highway overpass, no less than the majestic sweep of a river crossing reflects a creative integration of structure, func­ tion and form, skillfully executed in beautiful bridges of steel. To promote a more widespread appreciation of the aesthetics of steel bridges and to honor the architectural excellence of modern bridge design, the American Institute of Steel Construction sponsors an annual Prize Brid'ge Competition. Each year a distinguished Jury of Award, composed of leading art directors, architects and engineers, selects the steel bridges which it judges to be the most beautiful of those opened to traffic in the • United States during the previous year.
